The association schemes actually implemented
are fully centralized: the operator tries to maximize his utility
(revenue) by assigning the users to the different systems
[1]}-[2]}. However, distributed RRM mechanisms
are gaining in importance: Users may be allowed to make autonomous
decisions in a distributed way. This has lead to game theoretic
approaches to the association problems in wireless networks, as can
be found in [3]}-[4]}. The
potential inefficiency of such approaches have been known for a long
time. The term "The Tragedy of the Commons" has been frequently used
for this inefficiency [5]}; it describes a dilemma in
which multiple individuals acting independently in their own
self-interest can ultimately destroy a shared limited resource even
when it is clear that it is not in anyone's long term interest for
this to happen.
